Efficiency is one of the main focuses of the world, today. As the entire world relies on computers and networks, their efficiency is of utmost importance. Energy, processing power, storage and data access must all be used ...

Virtualization technology provides the foundation for building and managing reliable virtualized IT infrastructure by abstracting processors, memory, storage and networking resources into multiple virtual machines. As a ...

Queue management is a way to control congestion. There are two algorithms used with TCP protocol that are commonly utilized in nowadays network: Droptail and RED. Droptail is easy to implement but has the problems of lockout ...

Nowadays, Transmission Control Protocol (TCP) is widely used in 802.11 Wireless Local Area Networks (WLANs) because it can provide reliable communication connection between two hosts. This thesis discusses whether a base ...

The Internet as the biggest worldwide network provides a huge range of facilities and conveniences. Different types of communication applications are one of the most manifest conveniences provided up ...

Digital broadcasts are a highly efficient way of transmitting data to a large number of receivers, but they are typically not designed for reliable transmission. In this thesis we attempt to design a fully peer-to-peer ...

Modern Internet protocols demonstrate inefficient performance in those networks where the connectivity between end nodes has intermittent property due to dynamic topology or resource constraints. Network environments where ...

Linux-based operating systems such as MeeGo consist of thousands of modular packages. Compiling source code and packaging software is an automated but computationally heavy task. Fast and cost-efficient software building ...

With the advancements in DSP, mobile terminals are becoming smaller and smarter every day. The more the mobile becoming data centric, the more is the number of users from indoors. From radio network planning point of view, ...

The focus of this thesis is to perform and study indoor measurements with both HSPA+ and LTE MIMO setups. The reason behind this study is to validate the benefits of MIMO implementation in indoor cells. MIMO scheme is ...

Nowadays the high demand of data based services has become one of the key issues in the telecommunications sphere. Mobile cellular networks are thus willing to provide the necessary capacity that this growth demands. While ...

DC-DC converters, also known as switching voltage regulators, are one of the main components of a power management unit. Their main role is to provide a constant, smooth output voltage to power the electronic devices. ...

Long Term Evolution (LTE) is a high speed wireless technology based on OFDM. Unlike its predecessors, its bandwidth can be scaled from 1.6 MHz to 20 MHz. Maximum theoretical throughputs from the LTE network in downlink can ...

Long Term Evolution (LTE) has been designed with new architecture and features to meet user’s high data rates demand for a longer term in the future. 3rd Generation Part-nership Project (3GPP) has set the goals and targets ...

Use of multimedia services, such as streaming of high quality videos on mobile devices is increasing drastically which requires high data rate and bandwidth on mobile devices. Therefore LTE system is introduced by 3GPP ...

New types of service usages emerge every day in the Internet. Service usage could be Wireless Local Area Network (WLAN) usage or watching a streamed movie. Many of these services are commercial, so payment is often involved ...

The aim of this thesis is to design inertial sensor based activity recognition for a low power continuous sensing architecture for today's mobile technology using a dedicated low-power sensor processor. The system framework ...

Trust makes our life easier, as we can focus our resources to productive actions instead of verifying the actions of others. Many services in our society would not be possible without trust. We trust products and services ...
